Sony Pictures Entertainment objected to WikiLeaks' online release Thursday of a searchable database of more than 30,000 documents obtained by hackers in a massive cyberattack last year.

"The cyberattack on Sony Pictures was a malicious criminal act, and we strongly condemn the indexing of stolen employee and other private and privileged information on WikiLeaks,'' a company statement said.

Sony Pictures said it would "continue to fight for the safety, security, and privacy of our company.''

The stolen documents were made available to the media last year. They included embarrassing emails by then- Co-chairman Amy Pascal and personal information such as salaries and Social Security numbers of employees.

The release of 30,287 documents and 173,132 emails on WikiLeaks makes the information widely available and searchable.

WikiLeaks, an anti-secrecy website known for publishing classified U.S. government information, said it believed the documents belonged in the public domain.

"This archive shows the inner workings of an influential multinational corporation,'' WikiLeaks founder Julian Assange said in a statement. "It is newsworthy and at the center of a geopolitical conflict.''

The U.S. government had blamed the hack on North Korea after the reclusive nation was angered by the Sony comedy "The Interview,'' which depicted the fictional assassination of leader Kim Jong Un. North Korea denied it was involved in the attack.
